Previously mobile phones used to interfere with aircraft GPS systems. Today we see mobile phones incorporating GPS, and obviously they don't interfere with themselves. The GPS system on a aircraft is much different than a GPS IC on a phone, much more complex as it needs more accuracy.

AeroMobile developed a technology which enables users to SMS and use their data services on their phones without endangering the fate of the aircraft.

AeroMobile chief executive Bjorn-Taale Sandberg said: "We believe that the ability to communicate efficiently, easily and safely when on board flights will become an every-day feature of business and leisure travel very quickly.

“We have gone to considerable lengths to ensure that all safety and regulatory issues have been fully addressed, so we are pleased that Emirates has been able to join us in being first past the post in offering a full voice call service.”

"The evaluation of this new technology was a great success," Mr Borghetti said. "An overwhelming majority of passengers involved in the evaluation indicated they wanted access to inflight connectivity on an ongoing basis.

Calls during flight might infringe ethics, as in a close environment voice might affect some passengers' comfort.

For now, Qantas is only installing the system in Boeing 767-300 and Airbus A330-200.

Emirates enabled the same service, but only in flights between Dubai and Casablanca. Emirates lets users do voice calls unlike Qantas.

Air France was reportedly testing this service some type ago, and with enough pressure from mobile networks, we might see a strong incline towards calls "on-the-air"
